Please help with question 1


\fQuestion 1 5 pts Using the mtcars data set, determine the maximum value at 95% the confidence level for mean miles per gallon (mpg) for the population of six-cylinder cars. Put another way, fill in the blank: at 95% confidence, the mean miles per gallon for six-cylinder cars is at most mpg. You may assume the population is normally distributed. Answer to at least one decimal place. Question 2 5 pts Herd immunity depends on the fraction of a population that possesses antibodies to a disease. In this problem, you will determine the minimum population fraction, at the 99% confidence level, that does so, if in a random sample of 56 people, 17 test positive for the antibody. (Use the normal distribution as the approximation to the binomial distribution, and use the estimate p = p in calculating the confidence interval.) Express your answer as a percentage to one decimal place; that is, fill in the blank for the following statement: "at a 99% confidence level, at least __% of the population possesses the antibody."
